I shot some pictures yesterday in AdobeRGB instead of sRGB and almost all the pictures came out very blue, they I don't seem to be able to rescue them. I'll be shooting in sRGB for now and regard the whole thing as a failed experiment, but does anybody have an idea how this could have happened?

Colour spaces are a big topic. I've just started the thread Colour Spaces: sRGB, AdobeRGB or ProPhotoRGB which might help. Have a look at the colour gamut illustrations in the second post. I wonder how your image processing software and/or printer driver mapped the AdobeRGB colour space?

I'm not really sure, Bob. I do know that the blue coloring was also present on the screen of my camera... So i guess that means it shouldn't be because of faulty pc software (although the right software might have fixed it?)

there are a lot of variants....... lets deal with one at a time...... first can we see one of the shots that are blue.........

second....... you could reset your camera back to factory defaults then change to Adobe RGB 1998....... as you could have changed another setting in your camera that is not compatible with this setting...... its all easy

This sounds very much like a White Balance issue rather than a colour space issue.

Shooting in a different colour space should have absolutely no effect on the colour temp of an image. The only thing that (should) happen when you set your camera to Adobe RGB is that you're telling your camera that it can now use a wider catalogue of colours to interpret the information captured by the image sensor. (For example; You have two teachers. "Mrs sRGB" and "Mr Adobe RGB". Mrs sRGB only gives you 3 colour crayons to colour in your picture at school. Whereas Mr Adobe RGB gives you 10 different colour crayons.)

This should in no way cause everything to come out blue.

Have a look at what your camera's colour temperature settings are set to.
